onev end with vertically spaced threaded open- The partition 15 isthicker at its front end and` ings to receive the associated inlet and`outlet is disposed in line with a removable plug 16 in pipes of thewater system. `This member is of a the rear end wall, the thickened endlof said L': 10

partition tapering in a manner avoiding sharp corners in the vicinity ofthe ends of the pipes 5 and 6.

On the outside of the member 7 are longitudinally spaced ns or ribs 17which extend around the bottom and up the side walls of the member andpreferably all of said ribs except the one 17a adjacent the front wall11, taper off toward the top wall of the member which is devoid ofsuchribs. By omitting the ribs mentioned, from said top wall, thepossibilities of deposits ofashes and other products of combustion uponthe top wall of the member is avoided and which deposits would act as aheat insulation. The rib 17a is connected to the respective bosses 13and 14 by llets 17h which strengthens the member as a whole and preventsfracturingr of the casting` as a Whole at these points.

In the operation of the device, the heat rising from the fire bed isfirst absorbed by the fins or ribs 1T-"17d and then by the Various wallsof the device and is then conducted to the water within the generator.Areas of greater or intensied temperature areY produced in line with theribs as shown in Fig. ,1 with the result that reverse currents arecreated which increase turbulence of the Water to insure such a movementthereof as'to bring all portions thereof into intimate Contact with thevarious walls of the'v device. Thus the water absorbs a maximum numberof heat units in its passage through the generator.

As the member is always filledV with water and as this water is quiteturbulent, no water solids can remain inert upon the interior surfacesof the member long enough to adhere to the said surface and accumulatethereon. Thus the inner surface of the member remains constantly cleanso that'the device operates to its fullest eiiiciency in imparting heatunits to the water passing through the sama As the device provides achamber in the associated system of a cross sectional area greater thanthat of the pipes connected thereto, it acts as a relief expansionelement to eliminate water knocks so that the device is quiet inoperation.

' It is self cleaning, both inside and out, and it heats more Water to ahigher temperature than is possible with the return bend and pipes nowused for the same purpose and is much easier to install and may beproduced at a much lower cost.

While in describing the invention, I have referred in detail to the formand arrangement of the parts thereof, the same is to be consideredmerely as illustrative of one embodiment of the invention so that I donot wish to be limited thereto except as may be specifically set forthin the appended claims.

'1. A device of the kind described comprising an integral, fiat, hollowmember having side walls, top and bottom walls and end walls, one ofsaidend walls having spaced tubular bosses opening into the top and bottomof said member at one end, a longitudinal partition in said memberandextending from'said one of said end walls toward but terminatingshort of theother end Wall to form a U-shaped chamber in .said membercommunicating with said bosses and longitudinally spaced ribs on theexternal surface of the side and said bottom walls only of said member.f

2. A device of the kind described comprising an integral fiat hollowmember having sidewalls, top and bottom walls, there being asubstantially fiat wall at one end of the body and a substantiallyrounded wall at the other endrof the body, vertically spaced tubularbosses on said substantially iiat end of the body, a central par'-tition extending from said substantially fiat end of the body,longitudinally thereof Vtowardlout terminating short of thesubstantially rounded end of said member to provide a U-shaped channelcommunicating at its ends with said bosses and longitudinally spaced`ribs on the external surface of the side and bottom walls only of saidmember. f
